Resurrecting an old thread so that the documentation is in one place.
I have U13 on an NA-148VG4 and have removed the 3D sensor and used a meter with sharp probes to test all the fine wires – they are fine.
I also looked at the service manual on Partmaster and was able to run the service test for spin. This shows values for the x, y and z directions for the 3D sensor and then abruptly also goes U13.
any advice please as to whether to spend the £50 on swapping the 3D sensor or what else to look at?
The springs, weight and dampers are all in place and seem fine.
This is a fault rather than imbalance as the machine is bang on level and completely empty and still fails.
thanks!
